AMD: CPUs not vulnerable to Fallout and RIDL

In a brief statement, AMD confirmed that it doesn't think that the newly discovered Fallout and RIDL side-channel attacks affect its processors. These flaws affect Intel CPUs going back almost a decade, they were disclosed earlier this week.

At AMD we develop our products and services with security in mind. Based on our analysis and discussions with the researchers, we believe our products are not susceptible to ‘Fallout’ or ‘RIDL’ because of the hardware protection checks in our architecture. We have not been able to demonstrate these exploits on AMD products and are unaware of others having done so.
